Which Religions Are Growing?

Orson Scott Card has a nice essay this morning about John Paul II from a non-Catholic point of view.  I found this excerpt interesting:

The real division in Christianity today - and in other religions too, I might add - is between the churches and congregations and individuals who are accommodating themselves to the new secularity, abandoning doctrines and commandments in the process, and those that believe that God still requires us to live by faith and by obedience to his commandments, now as much as ever.

Here is one simple truth, borne out by statistics over many decades and generations:  The religions that demand of their members some real and rational degree of sacrifice, obedience, and adherence to faith are growing stronger and stronger; while the ones that say, in effect, that you can do what you want and God doesn't expect much of us anymore, except to be vaguely nice - they are losing members rapidly.
